3.13.15—System and Communications Protection - Derived

Authenticity protection includes protecting against man-in-the-middle attacks, session hijacking, and the insertion of false information into communications sessions. This requirement addresses communications protection at the session versus packet level (e.g., sessions in service-oriented architectures providing web-based services) and establishes grounds for confidence at both ends of communications sessions in ongoing identities of other parties and in the validity of information transmitted. [SP 800-77], [SP 800-95], and [SP 800-113] provide guidance on secure communications sessions.
